To all whom it may concern: 7

Be it known that I, HENRY MARLns, a subject of His Majesty the King of En land, residing at 24 Essex road, Manor Park, in the countyvof Essex, Kingdom of England, engineer, have invented certain 16W and useful Improvements in Closures or Stoppers for Bottles and other Vessels, of which the following is a specification.

This invention relates to improvements in closures or stoppers for bottles and other vessels, but more particularly the stoppers or faucets as they are called in the trade, commonly used on tin cans for petrol or motor spirit, or other inflammable volatile liquids, where a secure and eflicient stoppering device is a necessity. The present form of faucet as applied to the most common type of petrol tin comprises a neck part and a cap or stopper. The neck consisting of a short piece of metal tubing which is fixed upon the tin and opens into same. This short tube has a screw thread cut upon the outer surface of its projecting end.

The cap, or top of the faucet, consists of a short tubular part with a closed in end, like the lid of a pill box. And has upon the inside of its tubular part an internal screw thread for engaging with the external thread of the neck. A leather disk is usually employed to form a tight seating between the cap and the end of the neck. To enable the cap or top to be revolved for screwing up or unscrewing, it has projections upon its upper surface forming channels or openings between, into which a suitable tool or lever may be inserted. These caps requiring to be put on very tightly to prevent leakage or misplacement in handling, a fairly long lever is found necessary for the purpose, and consequently a similar lever or tool to unscrew the caps. And although the necessity for such a tool is no serious inconvenience in the filling sheds where the tins are handled in large quantities, it sometimes'becomes somewhat inconvenient when the tins are being opened singly by the users, who may not have a suitable lever at hand.

Now this invention has for its object the Specification of Letters Patent.

formation of a cap or faucet top that while making an equally secure and eilicient joint, can be readily removed by the thumb and finger without the aid of the usual tool or lever. The neck part remains substantially the same as before described and the cap consists of a tubular internally threaded part that engages with the external thread upon the neck. But instead of a solid closed in end made in one with the cap, the latteri made sectional and the tubular threaded part of the cap constituting one of the sections thereof has an internally projecting flange at its outward end, and between this flange and the'end of the neck is placed a substantially fiat metal disk forming the other section of the cap or stopper and closing the orifice of the neck and having between it and the neck end the usual leather washer or disk. Now this tubular threaded part of the said cap is cut asunder or parted at one point of its circumference, and'the two ends thus formed are connected or normally held together, and preferably in contact with one another, by a suitable removable or adjustable device such as a screw, clip, or pin, or one of their equivalents. l Vhe n a screw is employed, a lug is formed upon each adjacent end and the screw passing through the two lugs is made to hold the ends together. And by screwing up or unscrewing same the ends will be pulled together or opened out. This screw is provided with a slot in its head suitable for the insertion of the edge of a coin or other handy article for turning the screw with, or other means may be provided, such as a ring or fly nut projection to enable the said screw to be revolved by the thumb and finger. The idea being that before placing the-cap upon the threaded end of the neck this screw will be tightened up, holding the severed ends of the tubular portion close together. The cap being revolved and screwed on in the usual way, a suitable tool or lever being employed to tighten up same.

slacken or partly undo the screw which holds the severed ends of the tubular part together; this allows the same to expand and the internal thread upon it comes away from close contact with the threadedneck. so that the said cap may be easily revolved. and removed by the fingers. Any other form of device may be employed. that normally holds the severed ends of the said tubular part together while the cap is being screwed up and can be removed or slackened to allow same to expand to. facilitate removal. To enable this invention to be. more clearly understood I will now describesame with reference. to the accompanying draw- 1ngs:

Figure 1 is a side view of the type of faucet neck inv common use. Fig. 2 shows the same neck fitted with. .one of the. improved faucet caps or stoppers as described in this specification. 3 is .a plan view of the same cap. Fig. 4 1s a horizontal sec tion through line W. X. asshown in Fig. 2. Fig. 5 is a vertical section through line Z. Y. shown. in Fig. 3. Figs. 6, .7and 8 show screws, removed from cap, provided". with alternative means for revolving. said screws In Figs. 1 andv 2 the neck is provided with a loop of wire A, the sealing wireB .passing through this loop and through a hole D made for the purpose in the upper part of the cap E. This hole is seen in the section in Fig. 5. The object of this sealing wire being to prevent surreptitious. unscrewing of the cap, the wire being fastened by a seal S.

' In Fig. 3 the cut ordivision between. the lugs F G is closed up, in which position the cap is intended to be screwedon to the neck, Fig. 1. In the section Fig. i. this division or parting is shown open, the screw H having been unscrewed to allow-the head of same to come away from contact with the lug G through which. the screw .passes freely. The other end of screw H fitting the internally threaded. hole in lug F. As will be seen by this section Fig. 4, the threaded hole referred to is somewhat enlarged at its outer end and the end of the screw H is expanded so as to prevent the entire Withof the band. The disk J; instead of being quite fiat may be somewhat domed or raised as shown. The leather diskKisalso shown in place between the disk J and the top seating of the neck. This leather disk K is preferably somewhat larger than the diameterof the neck so that it slightly overlaps the seating as shown in the section and the cap E is recessed between the thread and the flange to allow room for this larger leather disk. The metallic disk J and the leather disk K extend into the annular groove E beyond the threads of the divided band, and the disk K, being flexible, is adapted to be removed. from the groove E without releasing the metallic disk. The metallic disk, the divided band, and the adjusting screw may be assembled prior to applying the flexiblevv disk to the cap.

Fig. 6 shows one of the screws H removed from the cap and fitted with a stamped fiat metal ring for turning same, Fig. 7 being another of these screws having a notch or out in its head to enable it to be revolved with a coin, screwdriver, or some such de- VlCe.

The. screw Fig. 8- is; provided with a kind of single fly nut projection for revolving same. This. projection might, of course, be extendedon both sides of the. head to. form a. double leverage for revolving the screw.

What I claim and desire to secure by LettersPatent of the United States is:-

1. A closure cap of the class described, including an internally threaded and divided band adapted to screw on the threaded neck of a receptacle and provided beyond the screw threads with an interior annular groove, a disk closing the outer portion of the opening of the band beyond the screw threads and having its peripheral edge arranged within the said groove, and adjusting means for engaging and connecting the divided ends of the band for holding the same together to enable the closure cap to be screwed tightly on the neck of the receptacle, and adapted to permit the band to expand and loosen on the neck to enable. the closure cap to be readily unscrewed and removed without releasing the metallic disk from. the said annular groove.

2. A closure cap of the class described including an internally threaded divided band adapted to screw on the threaded neck of a receptacle and provided beyond the threads with an interior annular groove, an

outer metallic disk closing the outer portion of the opening of the band beyond the screw threads thereof and having its periphery arranged within the said annular groove, an inner flexible disk arranged against the inner face of the outer disk and extending into the said annular groove and adapted to fit against the outer edge of the neck of the receptacle, and adjusting means for engaging and connecting the divided ends of the band for holding the same tightly together,

said adjusting means also permitting the my invention, I have signed my name in band to eipfand M1116. enablinglthe claphto be the presence of two subscribing Witnesses. unscrewe 'rom t e receptac e an t e inner disk removed from the annular groove HENRY MARLES' 5 Without releasing the outer metallic disk Witnesses:
